"The MLS market is one that we've got to look at. Robbie's a good shout - he's a good pro," Redknapp said.

"He would be the ideal type to have around for sure because he would give us something. I haven't spoken to him yet, but he would be an interesting player."

Redknapp brought Keane back to Tottenham in 2009 after he struggled to adapt following his move to Liverpool the previous summer, before appointing the striker as team captain in Ledley King's absence.

He would make a further 41 appearances for the north London club, scoring 11 goals in the process, before falling down the pecking order following the arrival of Peter Crouch and Rafael van der Vaart.

Keane also spent a loan spell at West Ham United during the 2010-11 season, before making the move to the MLS.

Should he move to Loftus Road this winter, it will be the second loan spell in England since his move to the United States, having made six appearances for Aston Villa during the 2012-13 campaign, scoring three goals.
